Brain implant used to restore paralyzed man’s sense of touch

in a story in extreme tech published today,  some details  of the  proof of concept  using   direct  brain implants to  control a robotic arm  are given. In the past  myo electric  impulses  from  surface electrodes  were  used to  control  prosthesisi but the  sensory feedback was always the  problem.Now that  a start is nm made to  close the  feed back loop we  may find  more  life like  artificial  upper extremities  soon ( hopefully)
